CARBURETER.

Specification of Letters Patent.

Patented Dec. 18, 1906.

To all whom it may concern:

Be it known that 1, JOHN M. KELLEY, a resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Im rovements in Carbureters; and I do here y declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to carbureters, and has for its objects to increase the efficiency of such apparatus and to accomplish this by a simple and compact construction and to provide it with certain means for the automatic regulation of the flow of the fluids employed.

The invention consists in the construction hereinafter described and pointed out.

In the accompanying drawings, Figure 1 is a vertical central section of preliminary, main, and finishing carbureters, a tank, an air and liquid forcing bell, and pipes being shown or indicated in full lines. Fig. 2 is an elevation showing modifications of the carbureters. Fig. 3 is an elevation showing a modified carbureter. Fig. 4 is a section of a valve to separate gases and liquid fluids.

Numeral 1 denotes an oil-tank having a charging-pipe 2 and a delivery-pi e 3, communicating with the bottom of t e tank to receive oil or other liquid fuel from the heaviest strata thereof.

4 is a pipe communicating with the upper part of the tank and adapted either for outflow of vapor or the inflow of liquid, as required by the operation of coacting parts.

5 is a pipe communicating with a pump and with pipe 3, whereby liquid may be drawn from the tank. 6 is a pipe whereby it may be forced into the upper art of a preliminary carbureter 7. Achec -valve 8 prevents return of oil in pipe 3, and a checkvalve 9 prevents its return from pipe-6.

1O denotes a pipe communicating with means, such as a tank and bell, (indicated at 11,) for forcing air into the upper part of the preliminary carbureter.

12 denotes the main carbureter, and 13 a pipe for withdrawing liquid residuum from its bottom. 15 is a pipe communicating with means for withdrawing said residuum and returning it to the tank, suitable checkvalves being indicated by 16 and 17.

The several carbureters and the for finishing or drying carbureted air enoted by 18) have central pipes 19, 20, and 21, respectively, which are open or perforated near the bottom of the carbureting-chamber to receive carbureted air. Pipe 19 extends above the preliminary carbureter 7 and from thence down to the u per part of the main carbureter. The caflhureted air ascending in the pipe drops any excess of liquid that may be forced up, and the air thus freed from such excess is carried down to the main carbureter through the extension which, together with the main art of pipe 19, constitutes a bent pipe. This pipe enables the preliminary carbureter to be mounted immediately over the main carbureter and aids to support it in that situation and provides that in carbureters having the particular situation and relation the carbureted air may ascend in the upper carbureter and be delivered to the top of the lower one. Said carbureter 7, supported above carbureter 12, has a pi e 22, which may extend slightly above the ottom of carbureter 7 to retain some oil therein. It opens into the upper part of carbureter 12 to discharge the residuum from the upper to the lower carbureter.

22 is a float-valve normally closing pipe 22. Pipe 20, receiving carbureted air at its foot, discharges it into pipe 21 in the finishing vessel 18. Said pipe 21 has an inlet 23 and exit 24 to and from 18, respectively, and is closed or stopped between these parts to compel carbureted air to pass about diaphragms to be described. Plugs or stops are denoted by 21 v The particular arrangement of carbureters and purifier economizes space and provides that each may be separately inspected, repaired, or renewed, and these results are attained by means that insure an eflicient operation.

Each carbureter and the purifier has a series of annular diaphragms 25 fixed to the inner wall of the vessel or carbureter body and inclined downwardly and provided with a central opening of larger diameter than the respective central pipe, as indicated in the drawings. The inner edge of these diaphragms may be turned up or provided with a small flange 14 to retain oil that descends through the fibrous material supported upon the diaphragms or shelves.

26 denotes reverselyinclined diaphragms or shelves fixed to the central pipes and extending to near the outer wall of the carbureters, which may also be provided with oil retaining flanges. Preferably the diaphragms of the purifier will have no oil-retaining flanges.

27 denotes fibrous or capillary material used in the main carbureter and which could also be employed, if desired, in the other carbureter without departing from the invention.

28 is a ring in the top of the main ca1'bu reter to prevent too speedy and direct escape of the oil from the diaphragms.

The delivery-pipe 21 communicates by a pipe 29 with the pipe 4, whereby vapor from the tank may pass by valve 30 into said pipe 21. The check-valve 30 has a stem guided. by a bar through which it freely plays. The stem is of such size and Weight that the pump returning the contents of pipe 15 cannot by pressure of air or mingled air and gas or vapor close it nor prevent the escape of such gaseous matter into the deliv ery-pipe 21. It is, however, a float-valve and will be closed when pipe 15 is sufficiently filled with oil, and thus close the pipe, so that residual oil can be forced into the tank.

In operation. a hydrocarbon or liquid fuel is forced from the tank into the upper part of the preliminary carbureter and there brought in contact with air introduced therein, the two fluids being intermingled by passing to and fro between the diaphragms. The air thus partially carbureted is forced into the main carbureter, which may be styled the carbureter proper, where the fluids, together with the overflow of surplus or residual oil from the preliminary carbureter, are further mingled by passing about the diaphragms and through suitable fibrous or capillary material. Residual oil is returned from carbureter 12 to the tank, as stated, and the carbureted air passes through pipe 20 to the finishing or drying vessel 18. In this the thoroughly-carbureted air is stripped of surplus oil, which may be drawn off or returned to the tank by a pipe 19 By preference the preliminary and finishing or drying vessel are supported directly above the carbureter proper.

Residual oil is drawn from each carbureter and from the purifier, but is reused and wholly utilized, or substantially so. The current of carbureted air is upward in each of the combined carbureters, whereby the heavier or unmixed vapor or liquid may be separated by gravity, this effect being accentuated in the stripping carbureter by the several diaphragms, which also aiford a final opportunity for a more thorough mingling of air and vapor. With the air thus carbureted is mingled through pipes 4 and 29 the lighter vapor that escapes from the comparatively cool tank situated in a separate room or place.

The construction thus far described is in the main identical with that described in my Patent No. 780,355, January 17, 1905, and the application is to that extent a division of the prior application.

In some cases I have found it practicable to omit the preliminary carbureter and connect the finishing or drying carbureter with the central uptake-pipe that conveys carbureted air from the main carbureter, as indicated in Fig. 2.

31 denotes additional or supporting means for distributing and intermingling the air and gasolene or equivalent, and in Fig. 3 a modification of such means is indicated at 32. The horizontal screens or distributers 31 and the vertical screens 32 may be used either with or without the inclined shelves and with or without other intermediate porous material.

As indicated in Fig. 2, inclined and vertical distributing shelves or diaphragms may be perforated for the more thorough division and intermingling of oil and air. In some cases inclined perforated shelves or diaphragms will be used in connection with perforated or capillary material such as indicated at 32.

Having thus described the invention, what I claim is 1. In a carbureting apparatus, a carbureter having a central outlet-pipe and oppositely-inclined diaphragms alternately connected to the pipe and to the carbureterwall, and capillary material supported on the diaphragm such diaphragms overlapping throughout practically their whole extent.

2. In a carbureting apparatus, a carbureter having a central carbureted-air-outlet pipe and oppositely-inclined diaphragms alternately connected to the pipe and to the carbureter-wall, the free edge of each being adjacent a proximate diaphragm, said pipe terminating beneath the diaphragms whereby it is adapted to serve as a carbureted-air exit.

3. In a carbureting apparatus, the main carbureter, the preliminary carbureter, the purifier, and means for circulating air and oil downwardly in both carbureters, the preliminary carbureter and the purifier being mounted on the main carbureter, the preliminary carbureter communicating directly with the upper part of the main carbureter and the purifier with its bottom.

4. In a carbureting apparatus, the main carbureter, the preliminary carbureter, the purifier, and means for circulating air and oil downwardly in both carbureters, said means comprising an airsupply pipe for the preliminary carbureter and the bent pipe for conveying carbureted air from the bottom of the preliminary carbureter to the top of the main or lower carbureter.

5. The combination of the preliminary carbureter, the main carbureter, the purifier, a delivery-pipe for carbureted air, means for charging the preliminary carbureter with air and liquid, and communicating conduits, whereby carbureted air ascends in each carbureter and finally passes into the deliverypipe, and the bent pipe whereby partiallycarbureted air is conducted upwardly from the bottom of the preliminary carbureter and then downwardly to the main carbureter.

6. The combination of the preliminary carbureter, the main carbureter, the purifier, a delivery-pipe for carbureted air, means for charging the preliminary carbureter with air and liquid fuel, and communicating conduits, whereby carbureted air ascends in each carbureter and passes lnto the dehvery-p1pe,

both the preliminary carbureter and purifier being situated directly over the main carbureter, said conduits including the bent pipe.

7. The combination of the preliminary carbureter, the purifier, a delivery-pipe for carbureted air, means for charging the preliminary carbureter with air and liquid fuel, and communicating conduits, whereby carbureted air ascends in each carbureter and in the purifier and passes into the delivery-pipe, the conduit for ascent in the preliminary carbureter having a downwardly-bent extension to carry carbureted air to the main carbureter, all as set forth, whereby the fluids flow three times the length of one carbureter, twice the length of another or main carbureter, and once the length of the purifier.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
